ASPHALT & CONCRETE
Quantification of intrinsic parameters
Concrete is known as a reliable and robust building material. However, like any other building material, concrete can degrade over time. Often this degradation is caused by ingress of harmful substances from the environment into the concrete. Often moisture fluctuations in combination with ingress salts or even CO2 from the air can lead to corrosion of the steel reinforcement, cracking and spalling.
Porosity and permeability of concrete are two key parameters which determine the resistance of concrete against ingress of harmful substances. With help of CT-scans these parameters can be quantified non-destructively.
